SHADE-HOLDER.

To all whom it may concern.'

Be it known that I, Hanvnr HUBBELL, a citizen of the United States, residing at Bridgeport, county of Fairfield, State of Connecticut, have invented an Improvement in Shade-Holders, of which the following is a specication.

This invention has for its object to provide a shade holder especially adapted for securing heavy shades to lamp sockets and provided with means for securely engaging the neck of the socket so that. all danger of the shade slipping off from the socket shall be done away with.

With this and other objects in view l have devised the novel shade holder which I will now describe referring to the accompanying drawing forming a part of this specilication and using'reference characters to indicate the several parts:

Figures 1, 2 and 3 are elevations partly broken away illustrating variant forms in which I have carried the invention into effect; Fig. 4c a detail plan view of the U- ring and nut shown in Figs. 2 and?) with the eye-shank in section; Fig. 5 a view of the eye detached; and Fig. 6 is a plan view of the swinging yoke detached.

10 denotes a shade, which may be of any ordinary or preferred shape or configuration, inay be rnade of any ordinary or preferred material as metal, porcelain or glass and is simply required to be provided with a central opening 11.

12 denotes an ordinary standard lamp socket which is shown as provided near its lamp attaching end with the usual external rib 13, and at its other end with the usual neck la. The opening 11 in the shade is made large enough to receive the rib freely.

15 denotes eyes which are placed on opposite sides of the opening. These eyes are provided with threaded Shanks 1G which pass through holes 17 in the shade and are engaged by nuts 18 on the under side of the shade. The ends of the shanks are prefer ably headed below the nuts as at 19 so as to make it impossible for the nuts to turn 0E.

2O denotes the swinging yoke as a whole whose Shanks 21 are provided with hooks Q2 which engage the eyes. At the central portion of the yoke the metal is curved and recurved to form spring arms 28 having between them a curved recess 24. The ends of the arms curve inward toward each other so that the arms will yield when pressed Specification of Letters Patent.

against the neck of a lamp socket and will close about it when the neck passes into the recess, thus retaining the yoke securely engaged with the neck of the socket and causing the entire weight of the shade to be supported above the dome of the socket so that it cannot become accidentally detached in use.

The form illustrated in Fig. 1 is the sinoplest possible form of the invention. The shanks of the eyes may be adjusted by means of the nuts to the height required to place the opening in the shade in alinement with the rib on the socket as clearly shown in Fig. 1, when the swinging yoke is engaged with the neck of a lainp socket. If preferred the eyes inay be made solid in the shade, or again instead of eyes with threaded shanks and nuts ordinary cotter pins may be used with the upper ends opened out to form eyes and the ends turned outward to retain thein in the shade. This forni is admirably adapted for large metal shades, the shade being held securely against the possibility of jarring ott or being detached by its own weight. n

rlhe forni illustrated in Fig. 2 may be used in connection with metal shades, but is especially adapted for use in connection with porcelain enameled shades where it is desirable that the eyes should not directly engage the shade. In this forni, the edge of the shade around the central opening is gripped between an angle ring 25 and a U-ring Q6. The U-ring is provided with a base 27, an outer tiange 28 upon the edge of which the shade rests and a threaded inner flange 29. The angle ring comprises a horizontal iiange 3() which is adapted to engage the shade upon the upper side and a threaded vertical flange 31 which is adapted to engage the thread of the U-ring. rlhe shanks 16 of the eyes pass freely through holes 32 in the shade and may be engaged by nuts 18 as before, or retained in any suitable manner, the ends of the shanks being headed as at 19 to prevent the nuts, if used, from jarring off. In assembling, the U -ring is placed on the under side of the shade at the central opening, the horizontal liange of the angle ring is placed over the shade and the vertical flange of the angle ring is passed through the central opening in the shade and turned into engagement with the threaded inner fiange of the U-ring, the portion of the shade surrounding the. central opening being thus gripped between `the U-ring and the angle ring. rIhe shade is attached in the same manner as before, the rib on the lamp socket lying within the angle ring as clearly shown in Fig. 2.

In the form illustrated in Fig. 3, I provide an additional fastening means which locks the shade to the lamp socket in such a manner as to prevent any movement of the shade and prevent the possibility of rattling. rlhe U and angle rings are used as before and in addition to these I use a contractile collar 33 which is provided with an internal groove 34 adapted to receive the rib on a lamp socket and below the rib with a thread 35, andv is divided vertically across as at 36, which permits the ring to be expanded in order to pass it over the rib of a socket and causes it to be self-retaining on the socket by its own resiliency.

In the forms illustrated in Figs. 2 and 3, the nuts if used are preferably made of substantially the form illustrated in Fig. e; that is, the outer sides of said nuts are curved to correspond with the curvature of the outer iange of the U-ring so as to hold them against rotation when in the assembled position, this curved side wall of the nuts being indicated by 37.

The operation is briefly as follows: In the forms illustrated in Figs. l and 2, it is simply necessary to place the shade in position over the lamp socket with rib 13 on the socket preferably lying within the opening in the shade in the form in Fig. l and within the angle ring in the form in Fig. 2, and then to swing the yoke upward into engagement with the neck of the socket, the sprintf arms yielding and clasping the neck which will then lie within curved recess 24. In both of these forms the entire weight ofthe shade is suspended from the neck of the socket. In assembling and disassembling, the yoke can, if required, be readily disconnected from the shade by springing the hooks out of engagement with the eyes.

In the form illustrated in Fig. 3, the shade has a double connection to the socket and is held securely against any lateral movement and against the possibility of rattling. rIhe contractile collar is first placed in engagement with the lamp socket, then the angle ring is turned into engagement with the collar and then the yoke is swung into engagement with the neck of the socket as before.

Having thus described my invention, I claim:

l. A shade holder comprising a U-ring having an outer flange to support a shade'f and a threaded inner flange, an angle ring adapted to engage the shade on the opposite side and having a flange engaging the U-ring, and a swinging yoke engaging the angle ring and adapted to engage the neck of a lamp socket.

2. A shade holder comprising a U-ring having an outer flange to support a shade and a threaded inner ange, an angle ring adapted to engage the shade on the opposite side and having a flange engaging the U- ring, eyes engaging the angle ring and a swinging yoke engaging the eyes and adapted to engage the neck of a lamp socket.

3. A shade holder comprising a U-ring having an outer flange tosupport a shade and a threaded inner flange, an angle ring adapted to engage the shade on the opposite side and having a flange engaging the U- ring, eyes attached to the angle ring and a swinging yoke engaging the eyes and adapted to engage the neck of a lamp socket.

1l. A shade holder comprising a threaded contractile collar adapted to engage a lamp socket, a U-ring having a threaded flange, an angle ring threaded to engage the U- ring and the collar, said rings being adapted to clamp a shade between them, and a swinging yoke connected to the angle ring and adapted to engage the neck of a lamp socket.

5. The combination with a lamp socket having a neck and an external rib, and a shade having a central opening, of U and angle rings threaded to engage each other and clamping the shade between them, a threaded contractile collar which is engaged by the angle ring and is provided with a groove to receive the rib o-n the lamp socket and a swinging yoke connected;` to the angle ringand having spring arms adapted to engage the neck of the lamp socket.

6. A shade holder comprising a threaded contractile collar adapted to engage a lamp socket, a U-ring having a threaded flange, an angle ring threaded to engage the U- ring and the collar, said rings being adapted to clamp a shade between them, eyes having threaded shanks engaging the angle ring, nuts on said shank and a swinging yoke having hooks engaging the eyes and spring arms adapted to engage the neck of a lamp socket.

In testimony whereof I afHX my signature in presence of two witnesses.
